Updating the .env file

[newtmex]

I am new to laravel, so when I updated the .env file, I did not update the APP_KEY variable, because I thought it was not necessary.
So when I ran the site with my XAMPP i get a blank page, when I run with starting a server with php artisan serve, i get an error about cipher, so #[this] (https://stackoverflow.com/questions/31512970/laravel-no-supported-encrypter-found-the-cipher-and-or-key-length-are-invalid) helped solve the issue.

Will be nice if you add the solution to the read.me file. thanks
